Development efforts on Blender 2.5 have been renewed with work on the Data API through RNA. This allows for automation of GUI building, and provides a solid basis for animatable properties throughout the database.

Brecht has done a great job in designing and implementing the RNA system, and works is being delegated in RNA-ifying our DNA (the very core of the Blender database and file format). I’ve started wrapping the Material and Nodetree datablocks in RNA.
